Hi, could anyone help me out with critical path? My teacher was useless and I don't know how to work it out at all, I went to see him and he even said he forgot how to do it so isn't that a brilliant sign 😒 would be much appreciated!

Yeah sure..
Each node there are two quadrants
1- the upper one is the EST - earliest start time
2- the lower one is the LFT - latest finish time

To work out EST:
Put a zero in the upper right had part of node 1
Then add the duration time of the activity to the EST of this activity to give the EST of the next activity

To work out LFT:
You work backwards
Give the last node of the project an LFT equal to its EST which is 110
Then working backwards from right to left.. subtract the duration of thr activity from the LFT of the node

Hope this helps. Sorry if I've confused you but it's easier if you read or illustrate from a diagram. If you would like a diagram then do PM
